K.V.
mystic is pretty good but i really like the versa tan better. i know they have it at suns up tanning and it does cost a bit more (like $5 more each time) but the color is more natural looking and the spray is finer and dries faster.
make sure to do a couple now before the big day. the barrier cream takes some getting used to as far as applying it goes. i was orange under my nails and on my heels with the mystic but because the versa is such a fine mist, the discoloring isn't as bad but you'll still want some practice.
i paid $70 for a set of 7 mystic at islands tanning and i paid $30 for 2 versa at suns up. the color lasts about a week before you notice it fading. be warned the stuff is addictive! i was going once a week all summer long!
